South Hilo Landfill - Operational Landfill in Hilo, Hawaii

South Hilo Landfill is an operational solid waste management facility located at 25 Aupuni Street in Hilo, Hawaii, United States. It serves the Hawaii County area and is classified as a landfill, a common disposal method for municipal solid waste in the region. The facility operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste landfills and Clean Air Act landfill gas rules. As a landfill in Hawaii, it must manage leachate and landfill gas to protect the island's sensitive groundwater and environment. South Hilo Landfill plays a key role in waste disposal for the Hilo community. Its location near the coast requires careful environmental management to prevent impacts on local ecosystems and groundwater resources.

Landfills in Hawaii face unique environmental challenges due to the islands' volcanic geology, high rainfall, and proximity to coastal waters. Leachate management is critical to prevent groundwater contamination, while landfill gas collection systems help reduce methane emissions. Community proximity and traffic from waste hauling are also important considerations for this facility.
